The One Sith have made the first move in expanding their empire today by laying claim to the planet Mustafar. Currently uninhabited and with no facilities present, this shows that there is the imminent growth of the One Sith. Their strategy is unknown but it seems that they are prepared to claim planets even if they may not have the resources to defend them all.

Currently no other faction has responded to this move, but it is almost certain that the other factions will take action in trying to claim the other planets before the Sith do.
